This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Ibanez MT10 Mostortion

It's New Years Eve and time for the last layout of 2019 and I'm pretty sure it's the 800th on the blog! So here's the Mostortion. Why is it called that? The CA3260E opamp at it's core is MOSFET based. Unfortunately, this chip has been discontinued, so building a straight clone may be a little difficult, but a regular dual opamp like a JRC4558 or TL072 will work just fine as well. It's pretty similar to a TS10, just with a MOSFET chip and 3-band EQ, which is pretty handy. Schematic and more info here. Should be able to squeeze it into a 1590B.

  4. Always amazing layout for perfboarder pride!

    Push this with whatever OD you have, first heaven just above your head.

    I wonder if so somebody request SD2Lead. Different Beast!

    Thank to you David, and Kevin Aion.

  5. Happy 2020! And thanks for this one! For the opamp, check for the CA3260EZ, that one should still be available. Original diodes were MA-165 but there's not much difference in sound when using 1N4148.

  7. Finally got around etching and building this one. Tried to stayed as close as possible to the original (CA3260E opamp, 2SC1815 for the buffers, MA165 clipping diodes). Haven't AB'd it yet but sounds great already. Thanks again!

    1. That's one of the best looking/cleanest etched boards I've ever seen! Awesome work!

    2. Thanks! It's also the great designs you make, they just print, transfer and etch in a great way.

  8. Does the CA3260EZ work like the original chip?

  9. My disk capacitor between tr6 and d5 was fried by a leaking battery. Cant read it or the board around it. What's the value?
